Rat-bite fever (Streptobacillus moniliformis infection)
ICD-10 A25 is a billable code used to indicate a diagnosis of rat-bite fever (streptobacillus moniliformis infection).
Rat-bite fever is a zoonotic infection caused by the bacterium Streptobacillus moniliformis, which is primarily transmitted to humans through bites or scratches from infected rats or through contact with their urine or feces. The disease can also be contracted through the ingestion of contaminated food or water. Symptoms typically appear 3 to 10 days after exposure and may include fever, chills, headache, muscle pain, and rash. In severe cases, complications such as endocarditis or septic arthritis can occur. Diagnosis is often made based on clinical presentation and history of exposure, and laboratory confirmation can be achieved through blood cultures or serological tests. Prompt treatment with antibiotics, such as penicillin or doxycycline, is essential to prevent serious complications. Public health measures focus on rodent control and educating communities about the risks associated with rodent exposure.
